spray nozzle from 8 to 24 inches
away from cleaning surface. If you
get spray nozzle too close, you may
damage surface being cleaned. It is
not recommended to get closer than 6
inches when cleaning tires.
5. Pressure Adjustment

effect of the pressure on the surface
being cleaned, vary the distance
between spray nozzle and the surface
being cleaned. The closer to the
surface the higher the ef

pressure. As you pull away from
the surface, the pressure effect will
reduce. For most effective cleaning,
keep the nozzle between 8 to 24
inches from surface being cleaned.
